While the automatic responses of the amygdala can still be of benefit to us even in modern society, these responses can lead us to overreact, or react inappropriately.

The symptoms vary in severity from a mild stomach upset and rash to anaphylactic reactions and breathing difficulties that can result in death.

For modern people, in most situations, this is not usually very healthy as our responses are often inappropriate when we are hijacked by the amygdala.
